Definitions

  • the invention relates to a fuel filter, in particular for the operation of internal combustion engines of vehicles.
  • the object of the invention is therefore to provide a fuel filter which can be operated in the suction mode, without the filter surface is reduced by the outgassing air. Furthermore, it must be prevented that uncleaned fuel reaches the clean side of the filter medium and thus contaminates the fuel. Furthermore, the fuel filter should be easy and inexpensive to produce. This object is achieved by the fuel filter according to claim 1.
  • the fuel filter according to the invention serves to purify fuel, such as diesel.
  • fuel such as diesel.
  • impurities from the fuel are removable, so that they can not damage a subsequent consumer.
  • the fuel filter is provided for cleaning fuels for internal combustion engines of vehicles, in particular when a water separation is required.
  • the fuel filter has a housing and a filter element disposed in the housing.
  • the housing has at least one inlet and one Outlet. Through the inlet, the fuel to be purified flows into the housing and through the outlet, the purified fuel flows out of the housing.
  • the housing may be made of metal and / or plastic. If the filter element is to be exchangeable in the housing, the housing must be openable. It makes sense here if the housing has a container and a lid.
  • the filter element is arranged in the housing such that a clean area is sealingly separated from a raw area.
  • the raw area communicates with the inlet and the clean area communicates with the outlet.
  • Between the raw area and the clean area at least one flow channel is provided, wherein the flow channel is arranged at a geodädisch upper area in the fuel filter.
  • the flow channel can be arranged on the housing itself or on the filter element.
  • the filter element preferably has a folded and annular closed filter medium, which is sealed end faces with end plates. In an arrangement of the flow channel on the filter element, this is preferably arranged on the upper end plate. Through the flow channel gases can be passed from the raw side to the clean side at a corresponding differential pressure.
  • the flow channel is surrounded by a wall, wherein the wall is part of the housing or filter element can be.
  • the wall corresponds to a porous, permeable to gases and fuel filter body sealing, the filter body is impermeable to contamination.
  • the filter body can be designed both as a three-dimensional porous body and as a flat or folded filter paper or filter fleece.
  • the filter body can eg be glued to the wall, welded or encapsulated by the wall.
  • the filter body completely covers the flow channel.
  • the pores of the filter body are designed such that gases which collect in the upper region of the housing can flow through the filter body from a defined differential pressure. As the gases pass through the filter body, the large gas bubbles can be broken up into very small bubbles.
  • the gas bubbles can also be split up and distributed into small bubbles through an aperture or a specially shaped edge along which the gas bubbles pass. These small bubbles can then be added to the purified fuel without adversely affecting the combustion process. If no gases are contained in the housing and the fuel comes into contact with the filter body, the fuel, which flows through the flow channel, is cleaned by the filter body. Thus, impurities do not pass from the raw area to the clean area.
  • For the gases to pass through the filter body is preferably a higher differential pressure than for the passage of the fuel through the filter medium required. This differential pressure is generated by the decrease in the liquid level in the fuel filter and the resulting, reduced filter area available.
  • a seal which causes leaks between the filter body and the wall are prevented.
  • the seal may consist of an elastomer which is resistant to the fuel.
  • the seal may consist of NBR or FPM.
  • resistance to diesel, biodiesel and ethanol is required to prevent damage to the seal and leakage.
  • a cage in which the porous filter body is at least partially arranged.
  • the filter body can be introduced for pre-assembly in the cage.
  • the filter body can be easily mounted in or on the housing.
  • the cage is permeable to the gases or fuel to be discharged, thus the filter body can be flowed in from all sides. This is advantageous, since in this way the effective, flow-through surface of the filter body is particularly large.
  • the cage has webs, wherein the webs are configured such that the filter body is held with an interference fit.
  • the mounting of the filter body in the housing is substantially simplified.
  • the seal is held with an interference fit in the cage, whereby the completely pre-assembled unit of the filter body, the cage and the seal can be fixed with a mounting operation in the housing.
  • the cage has snap hooks with which the cage can be fixed to the wall.
  • the preassembled unit is placed only on the wall and mounted with a light pressure.
  • the snap hooks and / or the wall may have chamfers to facilitate assembly.
  • the cage consists of a thermoplastic material which can be produced in the plastic injection molding process.
  • the cage is simple and inexpensive to produce, with complicated geometries can be realized.
  • the filter body consists of a sintered material, in particular ceramic. Due to the selection of materials or processing, the pores of the filter body can be influenced in their properties. It is advantageous if the pores in the area from about 50 to 150 ⁇ m, in particular 80 ⁇ m, since in this area an optimal passage of gas is ensured and the impurities from the fuel does not reach the clean area.
  • the ceramic filter body can be adapted in its pore size, porosity and cell geometry to the respective requirements.
  • the filter body may be formed by an open or closed-cell foam.
  • a preform may be used of a foam material that has been machined to the required geometries.
  • Possible foam materials are, for example, crosslinked polyethylenes, PUR ethers, cold foams of HR or CMHR, PUR esters, prepolymer foam, sponge rubber, latex foam, melamine resin foam, viscose foam, PVC foam, copolymer foam PANA elasturan, polypropylene foam, natural rubber, Chloroprene rubber, ethylene-propylene-diene rubber, nitrile-butadiene rubber or styrene-butadiene rubber.
  • any method such. As sawing, thermoforming, water jet or laser cutting can be used.
  • the shaped preform is infiltrated with a suitable suspension of inorganic sinterable particles by, for example, pouring over or dipping. Subsequently, the mold is dried in air or under defined conditions with respect to temperature and humidity. After drying, the filter body is sintered, forming the pores.
  • the filter body is cylindrical, wherein an end face is disposed above the flow channel.
  • the peripheral surface and the other end face are in contact with the raw area, whereby the filter body can be flowed axially and radially.
